Sovchem CTP Granule is a pre-vulcanization inhibitor that increases scorch time without effecting final vulcanizate properties. It inhibits scorch by acting as a MBT scavenger in sulfenamide and thiazole based cure systems. It is not as effective with dithiocarbamate and thiourea type accelerators. It is basically non-staining but may cause slight discoloration in white compounds.

Excellent retarder for most accelerators, especially good with sulfenamides. Excellent dispersion in NR. Used to stabilize the scorch time of uncured compound that is stored for long periods. Moisture less than 15%.
